I'm having this problem too, with Kubuntu Jaunty , last updates until today, ppa included. My graphic card is intel gma x3100 (chipset GM965).
At first, i think the problemas was with some plasmoid, but, today, i disabled all, and the problem continues. I disabled fsrunner (addon for krunner). This is not the problem. after 7 hours of running. free -m, report this: total used free shared buffers cached Mem: 2004 1928 75 0 7 1077 -/+ buffers/cache: 843 1160 Swap: 2368 1391 977 Top process (with htop or top) are always Xorg, and plasma-desktop.
